Asynchronous Transfer Mode. An industry standard for moving data. In an ESS
environment, ATM refers to the scheme used to connect Port Networks
together.
Cluster Identification number. In an ESS environment, the Module Identification
number (MID) found in the license file is referred to as the CLID. The CLID
identifies a unique cluster. Each server in a duplex pair has the same CLID. The
MID/CLID is set by the RFA license file and cannot be changed.
A cluster is a server or set of servers which share call state. The cluster can be
the singular case (S8500 series servers) or the duplex case (S8700 series
servers). This definition implies that servers within a cluster can be
interchanged if duplicated.
A virtual group consisting of one ESS server and one or more Port Networks.
Enterprise Survivable Servers: The Avaya option that provides survivability by
allowing backup servers to be placed in various locations in the customer's
network.
The server(s) that are ready to respond to an IPSI's request for service if all
other recovery mechanisms fail. The ESS may be simplex (S8500 series
servers), or duplex (S8700 series servers).
Local Survivable Processor: A media server (usually an S8300) that may
accept media gateway and/or endpoint registrations incase of a server or
network failure.
The primary server(s) that usually control the system. The Main server may be
simplex (S8500 series media servers), or duplex (S8700 series media servers).
